1. Award winner

Takeshi Shimada, Digital Development Department, Research and Development Headquarters, Proterial, Ltd.

2. Achievements awarded

Development of electroceramics, mainly on dielectric materials

3. Summary of achievements

This study clarified the mechanism of dielectric loss in dielectric materials for communications used in high frequency ranges, including the GHz band, by focusing on the interaction between acoustic phonons* and electromagnetic waves, with success achieved in developing a material with extremely low dielectric loss. This material has been applied to the mobile communications field, such as satellite communications and mobile phone base stations, greatly contributing to improving the performance of communications infrastructure.

Furthermore, the knowledge gained from this study has also been applied to semiconductor ceramics and high thermal conductive materials, and has been highly evaluated for its application to a wide range of fields.

Terminology

  1. *Acoustic phonon
    Called a quasiparticle, where the vibrations of crystals (lattice vibrations) transmitting sound and heat are treated as if they were a single particle.
